Multispectral Image Database

Click on the images below for a MATLAB .mat file containing full spectral resolution
reflectance data from 400nm to 700nm at 10nm steps (31 samples).
The image matrix for each object is 31xWIDTHxHEIGHT. The images have been captured
in a VeriVide viewing booth with a black cloth background under CIE illuminant
D75. Each image has been captured twice: once with a white tile and once without.
The illuminant has been estimated from the white tile and the spectral data
divided by this estimate, in order to arrive at reflectance measurements. The
images below are disaplyed sRGB values rendered under a neutral daylight (D65).
